RETURN WATER-FEED FORsTEAM-HEATING SYSTEMS.

SPECIFICATION forming part of Letters Patent N. v2'5,314,'aa.tea April14, 1903. Application filed Novemher`21, 1900. Serial No. 37,206. (Nomodel.)

To all whom t may concern;

Be it known that I, GILBERT F. BROWN, of Clinton, county of Dewitt,andState of Illinois, have invented certain new and useful Improvementsin Steam-Heating Systems, of which the following is a specification.

This invention relates to systems of returning the water ofcondensationfrom steampipes, &c., to the steam boiler or generator; andit has for its object to provide a simple and elfective means fordraining said steampipes of their water of condensation and returningthe same t0 the boiler through the inting, and connect the other endthereof to'the t blow-off pipe at'some point behind the blow- I olfcock, thereby producing a complete pipe connectionbetween differentVpoints -or sides of the boiler, through which a constant landstrong'circulation ofwater is maintained, thereby preventingr theclogging and burning out of the blow-0E. My present inventioncontemplates the utilization of the water-circulation system thusdescribed for the purpose of draining olf and returning tothe boiler thewater vof condensation which collects in the lowest parts of thesteam-pipes or other devices supplied by the boiler, and my preferredmeans for eifectin g this result are illustrated in the accompanyingdrawing, which is a vertical longitudinal section of a boiler auditssetting, showing my invention applied thereto. l

Referring .to the drawinginfdetail, A indicates the boiler, and B theboiler-setting, of a steam-generator of the ordinary or usualconstruction.

C is the usual blow-off pipe, tapping .the

boiler at its under side and passing throng-hV the setting B andterminating in a blow-ov Iand connected with a vertically-disposed pipeF, rising from the blow-0E pipe C, by means of an ordinary T- union G;The pipes E and F, as they constitutepractically a-single pipeconnection fromthe boiler to the blow-OE pipe, I term thecirculation-pipe, and the pipes E, F, and C, joined as shown,constitute,

fin eect, a complete Water-circulation system any suitableconnection-fas, forinstan'ce, the

pipe L. From the lowest point of this steampipe I extend a drain-pipe Itothe water-circulation system EF C, preferably connecting thedrain-pipe theretoat the T-union G in the manner plainly shown in thedrawing.

K indicates an ordinary check-valve interposed at any suitable' point inthe drainpipe I. j

Referring to the operation of the device, when the water in the boileris highly heated and steam'is being generated therefrom a constant flowof water is automatically set up and vmaintained through the boiler andthe pipe-circulation systemE F C in the direction indicated by thearrows,as is Well understood in devices of this character. Any water ofcondensation which may collect in the bottom of steam-pipe I-IWill flowthrough the drain-pipe I, past the check-valve K, and .will joinrthecirculating current of water in the pipes E F C at the union G, at whichpoint the circulation flow and the drain oware both in' the samevertical direction. Furthermore, the inductive action of the circulatingwater-current, on the principle of the Sprengel air-pump, aids theaction of gravity in effecting the draining of the steam-pipes. Thepresence of the check-valve K inthe drain pipe prevents at any-time thewater from the boiler backing up in thev drain-pipe and getting into thesteam-pipeor itsconnections.y Q

It will be understood that the pipe H may represent any of thesteam-circulation pipes loo steam-receptacle located above the plane ofthe top of the boiler, a drain-pipe from said steam pipe or receptaclehaving a Vertical section inline with and connected to the Verticalseetion of the circulation-pipe, and a check-valve interposed in saiddrain pipe, substantially as and for the purpose described.
